Method Detail

setFeatureWindowSize

public void setFeatureWindowSize(int n)

Specify the number of tokens on before and after the span to emit features for.

getFeatureWindowSize

public int getFeatureWindowSize()

setUseCharType

public void setUseCharType(boolean flag)

If set to true, produce features like "token.charTypePattern.Aaaa" for the word "Bill"

getUseCharType

public boolean getUseCharType()

setUseCompressedCharType

public void setUseCompressedCharType(boolean flag)

If set to true, produce features like "token.charTypePattern.Aa+" for the word "Bill".

getUseCompressedCharType

public boolean getUseCompressedCharType()

setTokenPropertyFeatures

public void setTokenPropertyFeatures(java.lang.String commaSeparatedTokenPropertyList)

Specify the token properties from the TextLabels environment that will be used as features. A value of '*' means to use all defined token properties.

extractFeatures

public void extractFeatures(Span s)

Description copied from class: SpanFE

Implement this with a specific set of SpanFE 'pipelines'. Each pipeline will typically start with 'start(span)' and end with 'emit()'.
